The old/new default only affects cases where both files are provided (which is a clear sign that the project is trying to be compatible with both the old and the new form). In such cases, it seems to me that we should pick the newer file -- that way, when we come to turn off support for the old names, we won't introduce a change in behavior. Okay I buy this.  I’ll prefer the new spelling. I'm not overly concerned about the warning. I think most affected people would be Xcode Clang users, so you guys should do whatever works best for you to transition your existing modules users. Hmm, after changing to prefer the new spelling, I’m not sure this is interesting enough anymore.  My primary concern was that we might accidentally hide errors in module.modulemap files by having stray module.map files around.

The advantage of checking for the old name first is that we save stat calls by looking for the more likely to hit name first.

That being the case, should we look for the new name first, and consider adding a warning if we find the old name?

The “.map” extension is unfortunate and we’d really like to move “.modulemap”; the best chance to change it is now, before first class support for user modules enters the picture.
