I give a damn for the performance if my filesystem doesn't prove stable.
And I think you can't deny that all reiserfs versions for 2.4 had issues
in that area. _IF_ reiserfs proves stable in the next time I don't see
any reason why this checks should stay in.

For example I've just turned of the debugging on my ext3-using boxens.
Not only ext3 has proven stable, but I also know that if it fails there
is still e2fsck which has proven absolutly reliable in the last years.

Another example is the write support I currently add to my freevxfs driver
(and no, I'm neither working for RedHat nor is it the VxFS module that
played a central role in your 3/2000 conspiration theories):  until it has
proven stable for a long time I will not even add a option to turn off
all the consistency checks I've added.  I'll give a damn if ext2, reiserfs
or VERITAS will beat me until it is stable.

I'm not in a position to decide it.  But if I'm asked for my opion (again)
the answer will depend on wether reiserfs will be more stable than now
at that point.
