True - I don't really think there's any good solution to this (besides
maybe convincing upstream to version their releases).

Maybe not. Perhaps the breakage from wrong hash is worse than the
potential breakage from newer versions. Also notice that the download
support falls back to our local copy on sources.buildroot.net if the
hash doesn't match.

Yes, we do:

git grep 'SOURCE =.*\.c$'
package/cache-calibrator/cache-calibrator.mk:CACHE_CALIBRATOR_SOURCE = calibrator.c
package/devmem2/devmem2.mk:DEVMEM2_SOURCE = devmem2.c
package/whetstone/whetstone.mk:WHETSTONE_SOURCE = whetstone.c
