I would be ok with a flag that raised an exception/halted if the restricted dynamicism was encountered, if it meant appreciable performance gains.
For every project I've worked on, and every project I've really become familiar with, the "magic" that requires these crazy levels of dynamicism can relatively easily be avoided, with more "standard" interfaces, and possibly a very slight increase in complexity presented to the library user.
I used to play with python magic frequently, but eventually realized my motivation was just some meta code-flex game I was playing, and it's almost certainly never worth it, if other developers are involved.
