Which is a pity. There is a large installed base of armv5 systems that
desperately need valgrind. I could find some mails in the valgrind-devel
archives that boil down to 1. armv5 support is not perfect, and 2. it
would be costly to make it perfect. Which is also a pity, because 1.
it's ok to have some pieces working better than others -- and what we
have is far better than nothing, 2. if there is no committed baseline,
there will be no improvements ("release early, release often"). Provide
code -- accept patches -- let the community, if any, support that part.
I personally would welcome if the decision would be reviewed.

As the OP also wrote, it's the periphery that makes this infeasible. If
it were, one could get fairly good results with valgrind on i386
instead.
With kind regards,
