A Soundsmith Denon dl103 retip question

I have been reading a lot about this mod and the improvements that are attained

E.g. - the general consensus of the Soundsmith ruby retip is a more detailed playback as the main benefit.

However, replacing the cantilever also replaces the tip with one of a different profile.

So my question is - are there a downside to this mod?

E.g.
- can microscopic particles of dirt in the groove become more audible making older albums sound worse?
- will a stiffer stylus make skipping due to scratches more of an issue

Anyone out there notice any negative side to this mod

Thanks
