Improving Plone and cleaning up things is always a good thing. But a 3.5 
major release will break the users expectations to have a stable 
backward compatible 3.x release cycle. It's also confusing to name a 
major version x.5 with all the consequences like incompatible 3.x 
Add-Ons. The naming of Plone 2.5 was a rather unfortunate thing. The 
proper naming for a backward incompatible release should be 4.0. I think 
nobody wants a short living 4.0 release and rename the current Plone 4 
to Plone 5.

I'm in favour to put as much changes into a 3.4 that are backward 
compatible. I think it's ok to change some defaults for new Sites that 
can be easily changed by an administrator like TinyMCE/optional 
packages/Additional Roles that can. Thus I don't now what consequences 
this would have for our documentation team.
Changes that bring other than really minor incompatibilities for 3.x 
add-ons are a no-go for a 3.x release imho.
