It's interesting to hear about HTML5 games that end up on consoles, even if they're not using Construct. However having a look at their blog, it sounds like they more or less ended up porting the game to standard native technology (e.g. porting/rewriting in C++), which is already the de facto way to port HTML5 games to console. There are already companies that port Construct games to console this way, such as Chowdren.
Also note the topic of Construct support on Switch has been discussed to death already and I'd prefer to avoid going through that all again in another thread. The current situation is Construct has built-in support for Xbox One (via UWP export), and for PS4/Switch you have to find a publisher who can do a port for you. Unfortunately as I've described many times in the past, it's very difficult to improve on that. The best approach is to keep asking Sony and Nintendo for support for HTML5 games.
