I agree that opening square bracket is useless, but I want to have the
directory and $/# character separated. This prompt is well established,
however I agree that we can probably get one character less with
something like
foo@localhost lib>$

Good suggestion, I like it - and maybe it would make sense to change the
default to this if wider audience will agree on that.
Still I don't agree that this is useless - I usually have several
terminals with ssh connection and they are differentiated in user (e.g.
per tool I'm using on that machine). Having only hostname will make it
harder for me (as the hostnames differ only in number). Most of the
users probably don't have this scenario, so I'm a bit toward to +1 here.
Greetings,
