Metzitza Bpeh is a Mesora, It should not be stopped unless absolutley necessary.
However I think that there should be a vaad which should oversee all mohalim.
there should be giudlines, which would include proper training, and saftey precautions.
The vaad should be have rabonim as well as mohalim and Docotors.
Each mohel would have to get certification, which would mean that he is well versed in halacha as well as in all saftey precations.
recertification would be needed after a preiod of time.
Just like we now require all bakeries to have a hashgacha certification, the same should apply for mohalem.
I think that this is common scents.
