Do you have experienced configurations where GENERIC and GENERIC_LAPTOP
+ using boot -d would not have helped?

I'm not sure whether it fills even that promise. Changes to GENERIC:
- optimised for size
- i386 and MATH_EMUL, the latter might be useful to add to GENERIC, the
former is considered to be essentially broken.
- PIC_DELAY (seems to be a dead option?)
- no red zone for userland (does the description even match for that?)
- much less mbuf clusters by default
- uses pccons instead of wscons in the case of INSTALL_TINY
besides the expected amount of removed drivers and options.

So I would say that it is mostly useless :-)
