I use the block editor on every new project and generally enjoy it. But I also prefer the control I get with classic themes. Block themes just aren’t as flexible or even necessary for me at this point.

I think the ability to add support for block template parts could be the best of both worlds. Provide clients with the access to things they’ll need, while keeping the rest under wraps.

Perhaps this will become more of the standard than having a binary choice in themes?
