With all due respect, sitemaps are the thing of the past in the year of 2016. They have virtually zero SEO benefits, assuming your site has good internal linking structure.
Check my osclass.work demo website if you like (enter site:osclass.work in google search box), I do not use any sitemap plugin at all, but it is crawled and indexed by Google just fine (I do run Full Breadcrumbs plugin, which I am the author of and it is part of my live demonstration). I know this may sound like a really bad advertising, but I am honestly telling the truth here and anyone may confront my claims. You can google yourself for sitemap relevance to verify - internal linking, which is hugely boosted with breadcrumbs on search pages and elsewhere with other links on your site are tremendously more beneficial, since they work in real-time (no cron required, no server load issues, no obsolete info when you delete spam or expired items until next cycle runs etc.) => tied with google fast crawling and auto-mapping algorithms your site will be indexed in no time with relevant pages.

I would like to tell you Sir that your assumptions are wrong.
First xml sitemap are truly beneficial because it gives you some sort of direct control over how crawler will interact with your website.
Straight from google.
Do I need a sitemap?
If your site’s pages are properly linked, our web crawlers can usually discover most of your site.
Even so, a sitemap can improve the crawling of your site, particularly if your site meets one of the following criteria:
Your site is really large. As a result, it’s more likely Google web crawlers might overlook crawling some of your new or recently updated pages.
Your site has a large archive of content pages that are isolated or well not linked to each other. If you site pages do not naturally reference each other, you can list them in a sitemap to ensure that Google does not overlook some of your pages.
Your site is new and has few external links to it. Googlebot and other web crawlers crawl the web by following links from one page to another. As a result, Google might not discover your pages if no other sites link to them.
Your site uses rich media content, is shown in Google News, or uses other sitemaps-compatible annotations. Google can take additional information from sitemaps into account for search, where appropriate.
Using a sitemap doesn't guarantee that all the items in your sitemap will be crawled and indexed, as Google processes rely on complex algorithms to schedule crawling. However, in most cases, your site will benefit from having a sitemap, and you'll never be penalized for having one.
Thats from google
What if you change your domain or permalink settings?
What if breadcrumb do not cover page which you want to add?
What if you want to know directly how many of your pages are indexed/left in google?
If you think that it is added for legacy reason than you are wrong as google would not give a big section in webmaster-tools to Sitemap related settings if they are not important.
I truly believe breadcrumbs help in telling crawlers to index other pages( Even more useful for visitors). Will google use that information? Depends on Google.
It has no comparison with breadcrumbs.
