I'm certainly not set on anything, yet. I'm just proposing. This is
one of those unfortunate problems where there is no one solution that
makes everyone happy. We may have to be satisfied with least-
In terms of SRV, I'm all for it. The catch is that libcurl doesn't
support them (which actually makes sense, however unfortunate it is
for this immediate problem - SRV was often proposed, but never
formally standardized for HTTP). No reason we can't support it in hkp/
hkps, of course. I already have some code to support SRV for the non-
curl HTTP handler in GPG, and it would be reasonably simple to port
this over to dereference (for example) hkps://spodhuis.org into https://sks.spodhuis.org:11372
We could thus guarantee that hkps supports SRV from day one.
