Application level stream isolation

If I proxy bitcoind on debian it automatically uses stream isolation for its connections to peers. I know that if I proxy bitcoind in workstation via it will automatically forward to gateway (because it says so here: Dev/anon-ws-disable-stacked-tor - Whonix), but will it still use stream isolation?

There are various quality degrees of stream isolation.

It’s not mixed with Tor Browser traffic since that uses a different SocksPort at least.

A dedicated port would be better.

Applications using (a) socks user name(s) appropriately have best stream isolation. In that case, it shouldn’t even matter if a shared (not a dedicated) SocksPort is being used, and that being reliable. These are upstream features of Tor or the application, unspecific to Whonix.
