I remember looking at this last week and thinking the same thing.  I
remember hacking on merge.pl years ago and optimizing to run really fast.
Even today there are RH folks who complain it still runs slow.

I thought the same as you, why not start using the upstream approach and
have one less thing to maintain/worry about in the fedora spec file.

But the major plus with using perl was you could cache the file in memory
and it only had to be read once.  With the script, files are read multiple
times which add to the delay.

There is really no way around it unless upstream converts to perl or
python or even 'c'.

So I would be torn and lean away from it until the speed improves.  I know
if this makes it to RHEL people would complain and it would get ripped out
in favor of the old way.

My two cents.
