But adding some intermediate solution with its own ABI and its own
forked specializations hinders (and might even prevent, if it's "good
enough") the proper solution of this topic.
It's not like such features are in super-high demand so we *want* and
*need* as much generalization and unification as possible, to utilize
economies of scale and such.
There's really just two ways forward that i can see (in terms of this
going upstream via the events/tracing/instrumentation tree that i
1) Do it properly generalized - as shown by the prototype patch.
I can give you all help that is needed for that: we can host
intermediate stages in -tip and we can push upstream step by
step. You won't have to maintain some large in-limbo set of
patches. 95% of the work you've identified will be warmly
welcome by everyone and will be utilized well beyond sandboxing!
That's not a bad starting position to get something controversial
upstream: most of the crazy trees are 95% crazy.
2) Give a compelling list of technical reasons why the
generalization is not desirable and thus go for a minimally
Option #2 does not apply because you've yourself stated that the
generalizations make a ton of sense (and even if you didnt state it
i'd make that point).
The option you seem to have opted for:
3) do it in a half-ways and limited fashion due to time constraints
and perceived upstream resistence
is not something that was a winning model in the past so i'm not
really interested in that.
