OK.  I will concede the need for the arch part then.  But it needs some 
changing.  As I said before, I would prefer soprovides detected by 
ending in ".so" in the provides array and I do not really like entries 
in the provides array automatically changing apart from versioning.  So...

provides=(foobar libfoo.so)

would result in

provides = foobar
provides = libfoo.so=6-x86_64   (does that order look right...?)

in the .PKGINFO file.

I am fairly sure that pacman can handle two packages providing different 
versions of libfoo.so but that needs checked.

A patch that did this would be very acceptable to me.
