Hi Lynne,

as someone who is using a number of custom filters, I can say that the "own branch with properly integrated filters" approach is a continuing source of trouble when rebasing or trying to apply it to different base branches. Even though these aren't really 3rd party filters, having a mechanism for it would make it much easier to maintain additional filters.
I don't want to argue about the specific approach as other will know better than me, but I'm sure that it's possible to find a nice non-complex way, no?
