[bitcoin-dev] Bitcoin is an experiment. Why don't we have an experimental hardfork?

Firstly, XT is controversial, not uncontroversial;
Second, this issue has been beat to death quite a while ago
Third, it poses major risks as a non-peer reviewed alt with a number
of problematic features (with the privacy problems recently mentioned
on this list being just one of them)
Fourth, it has not followed any semblance of process in terms of the
development funnel or BIPS process, with XT developers instead
choosing instead a dangerous path of hard forking bitcoin while being
well aware of miner voting on viable solutions which have followed

The following proposals
regardless of what you think of any one of them, are deserving of
attention (BIP 100 / BIP 101) and are being voted on as you read this
by miners. (BIP sipa is not yet numbered, and BIP 102 is a backup
/fallback option.)  BIP 100 is probably the best of these (note, in
part, it schedules a hardfork on testnet in September).

Contentious hard forks are bad for Bitcoin.
You may want to read this again if you haven't recently.

There is no basis for further promoting XT by suggesting that it
should even be tested.
