with "intrusive" i meant, that all modules are now compressed by default and
there is no switch to build them uncompressed.
so you change a long established default which may not be welcomed by
everyone and give no option for conservative people.

we should take care and not break things.
default uncompressed, compressed implented as an option is a better
strategy, imho.
discuss changing the default at a later time then.

How many people use the option to install an uncompressed kernel?
