Comment (by arma):
Clients use begindir so it's harder to fingerprint and prevent their
directory fetches.
Relays don't use begindir to avoid loading down the directory authorities
with ssl handshakes (heavyweight) simply for an http directory
publish/fetch (lightweight).
Load on directory authorities seems like it should come primarily from a)
clients that are bootstrapping, though we're hoping to resolve that
bottleneck with the fallback directory mirrors, and b) relays. It'd be a
shame to magnify part 'b' by a lot.
