Kernels not older that 4.15 don't need net-wireless/crda, see https://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/crda.git/tree/README#n8 The (+)crda USE flag should be replaced with an appropriate check for old kernel version and the WARNING_CFG80211_CRDA_SUPPORT be limited to only those older kernel versions.
The problem is that several other pieces have to be in place for this non-crda setup to work, the USE flag helps enforce those. But we can also add a kernel version check if you want. Even on >=4.15, you can use crda and it's actually the easiest (less reliant on specific kernel settings) way.
I'm adding a new check for <4.15, I think that is the best we can do for now. I think we do still need to keep the USE flag so that users can explicitly select the regulatory domain method they want, and the ebuild can (do its best to) check for all required support for that method.
