This is totally up to you, but I just wanted to suggest that if you wanted to, there are files available to make some of the messed up vertex weights on SL avatars to be, well, less messed up.
https://jira.secondlife.com/browse/STOR ... mentmoduleThese COULD be included in a viewer installation, instead of the default Linden made ones, but it's really only a small bandaid solution as it's all viewer side, not server side, so only the people using the files see the fix. It also might be too far of a deviation from using the official files for a viewer to implement, and if it became widespread it maybe could make LL less motivated to fix it... so I don't know. Just wanted to put it out there as an option.
