Oren, Ubit submitted a patch that makes ODE support varregions. It's
been pushed. Initial tests show that it works fine, but please check
that it works in your environments.

Varregions don't support ODE, therefore megaregions must remain.
It's important to keep support for ODE because it has significant
benefits over BulletSim:
Most importantly, ODE has consistently good performance, whereas
BulletSim sometimes gets into pathological states where it consumes
extremely high CPU and makes every avatar in the simulator freeze in
place. I reported this bug here:
http://opensimulator.org/mantis/view.php?id=6789#c26617 , but it's
still happening (I checked again last month). This is a huge problem
and it's the reason Kitely still uses ODE as the default physics
engine. (We provide BulletSim as an option, but we warn users against
using it.)
Second, BulletSim has some strange behavior that ODE doesn't. E.g., in
BulletSim my avatar can walk vertically up some large prims! That
doesn't happen with ODE.
Third, some users prefer ODE's behavior, and they have many scripts
that are fine-tuned for ODE. Switching to BulletSim would kill their
scripts.
If Varregions supported ODE then it would be ok to eliminate
megaregions. But until that happens, megaregions are important and
need to remain.

Yeah, don't worry, there's no rush. We'll wait for people's input.
Eventually support for megaregions will be dropped. The question
is whether to drop it on the next release or wait a few more months.

Diva,
I don't have any technical input but, I don't think a complete
input cannot be provided by posting this at the beginning of a 3
day holiday weekend in the US. Hopefully, a decision will not be
made over this weekend.

Yes, am fine with it when it get removed. it's not good.
But i expect some people that get sad because the still say

Hi everyone,
We're cleaning up a few things in the code, and came
across megaregions. Now that we have varregions, there
is a strong will among core devs to remove support for
megaregions, because they were just a temporary hack for
when viewers didn't understand spaces greater than 256m.
Now that they do, the hack seems unnecessary moving
forward. Megaregions implementation is contrived and
makes a lot code unnecessarily complicated.
Any objections to its removal?
