How much deference to early adopters? Was: [RFC] QA of manually set svn:mergeinfo

In r28213, I put some restrictions in place as to what values svn ps
svn:mergeinfo will permit (previously we allowed just about anything).
Most of these restrictions were already checked for in
svn_mergeinfo_parse(), except for one: mergeinfo with paths that map to
empty revisions. As
http://subversion.tigris.org/issues/show_bug.cgi?id=3029* discusses
these are redundant and best avoided. With r28213 The checks are done
by leveraging svn_mergeinfo_parse() and then performing a second check
for empty ranges.

I'd like to move the empty range check into svn_mergeinfo_parse(), but I
worry about users who have been working with trunk builds the last year
and have mergeinfo in their repositories with paths mapped to empty
ranges. Since svn_mergeinfo_parse() would error out when trying even
list their svn:mergeinfo it would be pretty hard for them to fix. *So
now for my real question*: How much deference should we give to those
users who have been using trunk builds?


* Yes, yes, I know as we battle with issue #2897 and all the "Big" (tm)
questions, that the small details like this don't get much attention,
but a fantastic new A-class office building with the three L's ain't
much if the toilets don't work.
