No. Not killing the _already existing_ local variables is what
'persistent-local is for. What I am proposing here is only relevant to
buffer-local and directory-local variables that are going to be loaded
anyway. The change will only affect _when_ they are loaded.

I do not propose to keep the local variable values from the previous
major mode. What I suggest is running a part of hack-local-variables
earlier. Either way, file/directory-local variables will be set in the
buffer.

Hope I clarified the confusion.
