📝 Original message:
BIPs are already the Bazaar style of evolution that simultaneously
allows flexibility and coordination/interoperability (since anyone can
create a BIP and they create an environment of discussion).
BOLTs are essentially one big BIP in the sense that they started as a
place for discussion but are now more rigid. BOLTs must be followed
strictly to ensure a node is interoperable with the network. And BOLTs
should be rigid, as rigid as any widely used BIP like 32 for example.
Even though BOLTs were flexible when being drafted their purpose has
changed from descriptive to prescriptive.
Any alternatives, or optional features should be extracted out of
BOLTs, written as BIPs. The BIP should then reference the BOLT and the
required flags set, messages sent, or alterations made to signal that
the BIP's feature is enabled.
A BOLT may at some point organically change to reference a BIP. For
example if a BIP was drafted as an optional feature but then becomes
more widespread and then turns out to be crucial for the proper
operation of the network then a BOLT can be changed to just reference
the BIP as mandatory. There isn't anything wrong with this.
All of the above would work exactly the same if there was a bLIP
repository instead. I don't see the value in having both bLIPs and
BIPs since AFAICT they seem to be functionally equivalent and BIPs are
not restricted to exclude lightning, and never have been.
I believe the reason this move to BIPs hasn't happened organically is
because many still perceive the BOLTs available for editing, so
changes continue to be made. If instead BOLTs were perceived as more
"consensus critical", not subject to change, and more people were
strongly encouraged to write specs for new lightning features
elsewhere (like the BIP repo) then you would see this issue of growing
BOLTs resolved.
