I think that it will be fairly common (e. g. everyone using lsp-mode)
will have to use that setting. I am afraid that even if I choose option 1
the distributions like spacemacs/doom will set it globally(because they
are allowed to be opinionated).

When you create a process you provide a bunch of settings(e. g.
:connection-type, :filter, :no-query). Can we make another property for
the read max size?

Thanks,
Ivan
