Mathias from MP2 Games here! Wanted to chime in since Chowdren was mentioned :)
MP2 partners and co-develops games with several Construct devs, where we bring in a lot of technical expertise for e.g. porting. For the devs we are working with, they are able to do amazing games exactly because they don't have to worry about porting and other technical details.
I don't think most Construct devs would be happy with a generally available exporter for consoles. In our experience, most games will require adjustments and sometimes low-level knowledge before they will run great on consoles. If Ashley & team also had to concern themselves with support for this, I don't think Construct would be the amazing tool that it is today.
Chowdren is also an advanced piece of software, and it has taken years of development and R&D to get to this point. Chowdren is unique in its approach where it compiles the entire Construct project (including events and scripts) to C++, and does complicated transformations like effect stack merging. If Ashley & team had to manage the same amount of complexity without limiting themselves to a feature subset, I don't think they would be able to move fast on features that users actually care about.
I've been working on Super Ubie Island 2 and getting really close to release and my target is consoles. I've reached out to the Chowdren team a few times but I think they have a max capacity of how many projects they can work on. So i feel stuck. a lot of companies have told me they'll have to remake the game in Unity in order for it to run on consoles.
When I started working on Ubie 2, I had a lot of developers ask why I'm still using Construct when it doesn't support consoles. So I can only assume that most devs that tend to target console release have chosen other tools. But I'm not 100 percent on that, of course.
I do wish there were options out there but I feel stuck.
