Then every jack app would need to implement this. More replicated code
with more potential bugs. IMHO a cleaner solution would be to remove the
option from jack_client_open() and always force the use of the env
variable and let libjack deal with it.
If a client really needs to set the server-name it can use setenv()
before calling jack_client_open().

Anyway, it's too late now to change the semantics of the API.

You don't know newbies: "Oh, a 'Name' field, nice I'll name my server
before reading any documentation."

And no, telling a casual musician to read the jack documentation first
is not the way to go, either.

Old qjackctl was partly responsible. The server-name field was very
prominent top-middle of the settings dialog and also the only centered
item which made it stick out visually.
This has meanwhile been addressed (not removed, but simply moved to an
"advanced" pane).

Did someone suggest to remove features or make things impossible? I was
under the impression that this is about clarifying and simplifying
issues that are too complex or confusing for their own good.
