Upgrading from 4.0.2 to 4.0.3 question regarding reverted templates

[Jabong82]

I need help doing this.

Every time there is an upgrade, there are "templates that need to be reverted". In the latest update these include the header, forumhome, forumdisplay etc., which are all heavily edited templates for me.

So am I basically screwed every time there is an upgrade in that I will have to revert all the templates and then re-do all these edits for my mods? So there basically is no way around this?

Thanks in advance.
