No.  We are not communicating here.  The relative maturity of the
plugin that needs it is not relevant.  Just that there is some plugin
that could take advantage of it.

If ICI and/or MELT and/or Dehydra and/or whatever other plugin people
are developing need new plugin events, then by all means lets add
them!

Then I believe that me Basile & Diego have the same position, while Richard Guenther did express an incompatibly different position in the past (or perhaps I Basile misunderstood what he Richard meant by theory).

So I understood that people could propose new plugin events, provided that they are not too costly to implement (mostly meaning that the invoke_register_plugins calling them does not slow down compilations not using plugins), and provided people can explain clearly why they need it. It is not necessary to have a useful plugin coded & runnable to show the need of the event.

Thanks for the clarification.

Regards.
