No, just the opposite.  From my perspective, the pressure to get new
features into 3.4 prior to the end of stage1 has been greater than
in 3.[1-2] and 3.3.  This seems to have continued into stage2.  As a result,
a lot more of my time has been spent tracking the cause of bootstrap
failures.  It has been more difficult to keep the PA port in a working
state.  There is no question in my mind that this has taken time away
from maintaining the backend.

I am frustrated because we have had a bootstrap failure building
gnat on the hppa-linux port for a few months:

stage2/xgcc -Bstage2/ -B/home/dave/opt/gnu/hppa-linux/bin/ -c -gstabs -O2      -
gnatpg -gnata -I- -I. -Iada -I../../gcc/gcc/ada ../../gcc/gcc/ada/csets.adb -o a

I presented a potential solution but it was rejected, not because it
didn't work, but because the reviewer felt that a totally different
solution would be better.  This is consistent with what you are
suggesting but it doesn't get us any closer to a fix.
