The fact that it may will switch to another coin in the future does not matter IMO.
It does matter now, right?
You are wrong, bitcoin-xt MAY switch to another currency.
Bitcoin-XT will NOT switch to another currency if it does not hit its target of 75% of miners. Bitcoin-XT has been around for years, it is a Bitcoin client just like any others, it has some extra features not in Bitcoin Core and many people ran it for specific purposes. If it doesn't hit 75% then it will wont switch to another currency and continue to be used by many as a normal Bitcoin client.
May, will, might, those are all keywords. The important bit is that they
to else it wouldn't exist in the first place.
