Do you have any opinion on specifying the client names in your
recommendation? and the list of client names in "descriptor" and "intro"
should be independent.

However, what i am currently think of is that we can use the existing
format.

HiddenServiceAuthorizeClient auth-type client-name,client-name,...

But instead of allowing only two auth-types "descriptor" and "intro", we
allow another type called "default" which includes both "descriptor" and
"intro"

So if I put an option:
HiddenServiceAuthorizeClient default client-name,client-name,...

It will be equivalent to two lines of:
HiddenServiceAuthorizeClient descriptor client-name,client-name,...
HiddenServiceAuthorizeClient intro client-name,client-name,...

And on the client side, if I put an option:
HidServAuth onion-address default x25519-private-key ed25519-private-key

It will be equivalent to two lines of:
HidServAuth onion-address descriptor x25519-private-key
HidServAuth onion-address intro ed25519-private-key


What do you all think?

Cheers,
