Sure but this is a bit misleading. The risk isn't that 3.0 is not
widely accepted quickly. The risk is that the community splits in two.
And the suggestion is not for backwards compatibility in 3.0, but
forwards compatibility in 2.6.

So the question is rather: Do you want to disk a community split, or
add forwards compatibility?

But as I noted, if it turns out to be necessary to add that forwards
compatibility, it's always possible to do a 2.7 that has it.

I have loads of experience in writing code for evolving APIs, this is
how things have been done in the Zope community for years. It's not a
problem. It does not lead to fragile code.
