As with the current count of onions, it's not intentional harm,
just people wanting to do things. Bitcoin is bringing a big growth
in onion sites (litle impact itself). But the new bitcoin version
can interop with clearnet and onions natively. If I remember from
my last test, bitcoin rotates its traffic through a sizable address
pool. Multiply that by the userbase and it could be similar to

There might be utility in allowing different circuit expiry parameter
settings for different socksports... perhaps keeping a large state
table for some would reduce load.

Related at a distance is that I think the Phantom project mentioned
they will not hesitate to use disk to support the network protocol.

I want to get around to make some nice HS metrics along that ticket,
but I don't want to give early hopes.

Yes this is nicer.
