Compared to most alts Bitcoin's development already
is moving at a glacial pace

And for good reason! But I fear increasing the political overhead would pretty much halt development and possibly even increase developer attrition.
@HeRetiK: I agree with you, and I'm beating a dead horse at this point, but I have a different definition of "glacial" and would much prefer it if the design was basically set in stone, never to be tweaked again. I don't have the same appetite for improvements that most people seem to.
Of course, that's blithely ignoring real issues like quantum cryptography, but I suspect that even once Bitcoin is "post-quantum" there will still be many more upgrades than are strictly necessary, with each one being an opportunity to get something wrong, with possibly disastrous consequences.
I intentionally worded it like that, because I already addressed why its not encouraged in my first reply (i.e. the protocol becomes the least common demoninator, which is exactly what the protocol architects do not want).
@NotATether: Yup, can't argue with that.
