On a personal level, I do re-arrange the panel layout.

On a practical level, we create new panels every time you use the query
tool or debugger, or open properties dialogues etc.

Sure, but the main issue is that projects get abandoned all the time. We
have no way of knowing what will get dropped and what won't until it
actually happens - and even then it's not always clear, for example the
wcDocker case where there haven't been code changes in some time, but the
lead developer is still responding to issues very promptly.

My point is that it's very hard to know when a component needs to be
replaced, unless the team actually announces its EOL, and even then some
components require a huge amount of effort to replace them, when in reality
forking them and maintaining the fork may require significantly less effort.
