funny you should mention that; see PR 37349 :-)

It strikes me as a bad idea from a parsing perspective. Also, it seems
like it shouldn't be necessary (if I understand what it's supposed to
mean) in combination with .undef .MAKE.EXPORTED.

Pity the whole thing doesn't work like .SUFFIXES though for
consistency, but it seems to be a little too late for that.
