I think most devs would have the flexibility of mind to adjust to whatever framework (or whatever ad-hoc, informally-specified implementation of half a framework) you use in-house. Many of the frameworks are not very different and lean heavily on the stdlib anyway, this is not rocket science, frameworks have different uses and strong points and the community does not have to be divided in religious war between different frameworks or framework advocates and the church of the one pure stdlib.
These are tools, not competing world-views.
