It seems unlikely that HAproxy terminates TLS, posesses certificates
for all the ultimate end-points and initiates another TLS connection
to the target service. So, as a default, I would guess that the
proxy protocol never runs inside TLS. Given the current code,
getting confirmation for the hunch from the user community before
an incompatible change seems sensible.
