I don't think we should put any Bitcoin users at additional risk to help altcoins. If they fork the code they are making maintenance their own responsibly.

It's hard to disclose a bitcoin vulnerability considering the network is decentralised and core can't force everyone to update. Maybe a timeout period for vulnerabilities could be decided. People might be expected to patched before then at which point the vulnerability can be published. Is that not already sort of how it works?

I believe there continues to be concern over a number of altcoins which
are running old, unpatched forks of Bitcoin Core, making it rather
difficult to disclose issues without putting people at risk (see, eg,
some of the dos issues which are preventing release of the alert key).
I'd encourage the list to have a discussion about what reasonable
approaches could be taken there.
