If I can ask, how would this affect longterm viability of Bitcoin? Or is it a nonissue at the moment?
John Newberry said that :
In case it's not clear: no-one should run btc1 code. It is untested, unreviewed, buggy and can only serve to disrupt and confuse the Bitcoin network.
So if the code runs, it will leave and confuse the whole network and will leave a lot of problem to us users. miners and developers.
