Yes, the BFD code was making the whole exec code a lot more complex to
understand.  Since even the TODO talks about ditching it away, and
reviving and maintaining it would be a burden, it's better to just not
keep it, and have readable exec instead.

At least to show flexibility of the exec server. The difference between
the BFD code and the gzip/bzip2 code is that the latter makes the whole
exec code complex, while the gzip/bzip2 support only has a couple of
hooks, so even if the feature doesn't seem so appealing, the maintenance
cost is light.
