I don't know if this should be mentioned in the bip because it may change at some point in the future... Yet, changing it may cause a fork of the network (extremely unlikely but possible).

This shouldn't cause a fork of the network...

Imagine I released bitcoin-xxl with twice the MAX_SUBVERSION_LENGTH == 512. The UA string keeps growing over time and reaches maybe 300 bytes some time. Now it's impossible to connect bitcoin-xxl nodes with bitcoin-core 0.11 nodes, potentially splitting the network?

Your XXL node will talk to old/non-spammy XXL nodes which will talk to Core nodes, so no big deal.

MAX_SUBVERSION_LENGTH = 256

Maybe it's better to just "recommend" the implementation bitcoin-core does/did and link to the PRs...

Also, ping @luke-jr Could you please enable the GitHub issue tracker for this repo?

@MarcoFalke Discussion of BIPs should be on the bitcoin-dev mailing list, not GitHub.

@genjix @phantomcircuit May I close this unmerged?
