Uninstaller signing

I know this topic has been discussed a lot and I have gone through all of them. I wanted to share something that I did and works for me, but wanted to know if this will have any repercussions.
--Installed my product on local machine.
--Grabbed the uninst.exe , signed it through an external process.
--I add the uninst.exe as a file now in the installer instead of the "write installer".

I did a few regressions and I don't see any problems with this yet. I am assuming if my uninstall code changes, I have to repeat the above?

This is the same thing as some of the scripts that do !system '"${nsisdir}\makensis" -Dgenuninst "${__FILE__}"' + !system 'generateuninst.exe' on themselves, just more manual work on your part but it is completely OK to do it this way...

Thanks Anders .
I don't think the uninstall code will ever change for my installer, so should be good i guess.
