I don't think declaring it explicitly is helpful given in most cases (and even more now after recent cleanups), it's relied upon without declaring it anyway. Use within IUSE while it's implicit also means IUSE seems to regularly get out of sync with actual use within the ebuilds. As for removing implicit use entirely: while you might argue this could be okay for the Linux kernel, it would cause unnecessary rebuilds indefinitely whenever we add a new dep to an ebuild for e.g. Darwin, or if we did it for libcs, for say, musl/non-glibc. best, sam
