I would personally love a (temptative) development road map. Doesn't need to be very precise, but I am sure the devs have some rough goals in terms of timing, and it would be very positive to know them.
Most, if not all "Roadmaps" by coins so far have been nothing but promises; we aren't a fan of that.
The missives state what we work on and also what comes next, giving timelines helps no one.
I didn't mean the usual "Pump roadmap" you can see in most of the alts. I hope you're not fan of that, neither I am.
But something much more general would be useful, here I disagree with you that it helps no one.
If we want an economy to build around, boosted by technical projects, there got to be a little bit of info for them, even if completely indicative. For instance knowing a rough schedule for the multisig implementation is useful to develop services that might use it. A rough schedule can be just "probably closer to 6 months than to 2 months".
The community is smart enough to know it's all temptative, you shouldn't be scared to say what are your feelings. The core team cannot develop an entire ecosystem, you got to give a minimal info to potential innovators around you at one point.
