I don't think using 'declare' or a plist can be characterized as
"arduous".

It's not the extension per se, it's the fact that it causes
difficulties, as mentioned in this thread.  they may be small
difficulties, but the alternatives avoid them completely, and aren't
more complex.  I think using one of the alternatives will leave more
developers happy, and that in itself is a significant advantage, IMO.
