I'm don't think thousands of entries in sysfs is really a good idea. Even if you fix the the insert algorithm issues a simple ls will still be very slow and there will be likely other issues too. And nobody can claim that's a good interface.
This really needs a better a interface. e.g. add some wildcard entry as it was earlier proposed. and only generate the wildcard when some threshold is exceeded.
