I think Alexander raised the concern one year ago and there was barely any
feedback nor interest in helping.
Decisions being made based on feedback and available workforce, people
should speak up :)

People having to support 32bit systems then should support 32bit support on
OI ;)

If we lived in a dreamland of unlimited resources I would agree.

Indeed it would be nice to have someone working on the installer if you
have an interest in that.
