In https://github.com/snapcore/snapd/pull/1598#issuecomment-239952977 I discussed the next steps if there was ever a case for a fuse-control interface. It seems like there is now and I would much prefer implementing that instead of granting applications classic.
I’ll put it on my todo and will try to get this in for 2.37, however, if you wanted to take a crack at updating snapd, the security policy is laid out in the above url.
