The other reason I feel like hugepd may or may not be further developed for
new features like large folio is that I saw Power9 started to shift to
radix pgtables, and afaics hugepd is only supported in hash tables

That alone sounds like a good reason to not bother.  So unless more
qualified people have a different opinion I'm fine with this patch
as long as you leave a comment in place, and ammend the commit message
with some of the very useful information from your mail.
