Bisection divides users and developers

All I can think of: how can any developer require a user to grok using git at all. The amount
of people savvy enough to do a bisect will be very very small.
Having someone actually reporting a bug is probably the tip of the iceberg.
Volunteering and working in your own time, but if one contributes buggy code, one should
either facilitate in debugging and fixing it or not submitting it in the first place.
It's in everyone's interest not to piss off or push away participation from the
non-(kernel)-hackers section of the FOSS community.
I'm not quite sure if it would be feasible, but having a repository of installable kernels in
various staged (i.e. patches applied) of the process would help.
