Only if people are happy to download a separate tool for every
individual purpose. The advantage of osmosis is that it combines lots
of operations into a single tool. I haven't invented much new
functionality, simply looked at what a bunch of individual scripts have
done and made them easier to access.
Quite seriously, if you can write a tool that is more than 20% faster
than osmosis then by all means go for it. If it suits people's needs
I'll eventually roll similar functionality into osmosis.
Of course I'd be far happier if you could send me a patch to improve
osmosis functionality but that's your choice.
