I wouldn't really be fussed at having more than one way, but the more ways of publicising things the more things I (publisher) have to do, and the more likely that someone hasn't done the one I (consumer) am expecting.
And this doesn't cover all Linked Data - only those sites that offer SPARQL endpoints.

But digging deeper, what are you proposing?
That /.well-known/sparql is the SPARQL endpoint?
Or that it tells me where the SPARQL endpoint(s) is/are?

So I went an read the manual (I know, but it's Christmas!)
"As such, the well-known URI space was created with the expectation
   that it will be used to make site-wide policy information and other
   metadata available directly (if sufficiently concise), or provide
   references to other URIs that provide such metadata."

So I read that as it should tell me where the endpoints are.
Which is what sitemap.xml does.
So if the proposal was for /.well-known/semantic-sitemap.xml or something like that, then maybe.
But sitemap.xml as it stands doesn't have to be at the root of the domain, whereas .well-known does (I think).

So I think this would just be a distraction - it is much better that people actually generate the data for their sitemaps than spend time defining another way of doing something that many people won't bother providing or looking for.

To put it bluntly:
If you have already done a sitemap on your existing data or your consuming software looks at others' sitemaps then you are allowed to support this, otherwise go away and implement the existing de facto standard and come back when you have.

Oh, and Merry Christmas and a Happy New Year to you all!
