I think nosurvey will be the best compromise (when I can get the nosurveys to stop crashing the extended elevations).

I can set it to approximate and duplicate, so that is shows up yellow and dashed with my metapost customisation.

However

> nosurvey is nosurvey.

True, in the labyrinths of Therion maybe.

However I don’t think ‘nosurvey’ legs are distinguished from other survey leg types in the outputs, so not necessarily ‘nosurvey’ in the mind of those viewing the outputs.

Unless I am missing something…

How is the recipient of these outputs to know that there is a ‘nosurvey leg?

In the outputs below, there are perhaps subtle clues because I have included splays and passage walls, but nothing that would stand out to an inexperienced recipient.
