Yes, Yes, please! What about showing the QGIS application first and THEN
start loading (in background) the plugins (and other registring
components), showing the 'loading further components...' in the statusbar?

I'm in a governamental environment now, running QGIS in thin-client
enviroments, and the startup time of QGIS is horrible there (like
several minutes sometimes).

great.

It is not clear to me what the exact implications are, but given you can
reload plugins during a QGIS run, it looks to me feasible?

A fast starting application is always a good PR starter...
