Alan,
You're right, I don't think I've ever seen a standard corridor alignment which required the use of the chord bearing over the tangent bearing.
My use case is in recreating property boundaries. It's helpful when georeferencing a site using data that doesn't otherwise contain any control.
The worst-case scenario for this type of task is to receive the bare minimum amount of information on only a few pages of non-vectored PDF's, including basis-of-bearing, section monuments, and a property line which includes non-tangential curves.
My main thought is that TBC has so many survey tools and commands, but it doesn't quite have all the tools available to recreate select bearing-distance shapes without workarounds.

Have you checked project settings as there are alternative input methods for alignments that you can select there.
Look under view - Alignment editor
If you have arcs to enter by that method you may find them easier to create using the linestring editor and then convert to an alignment.
I can't say that I have ever had to create alignments in any way other than Geometrical or PI based inputs - chord bearing if i got that I guess I would draw using a polyline and then fit the curves to the frame I suppose.
Would love to see the plan sheet where those are provided where the normal data is missing - is that a state dot job or a rail job - if a rail job then you can pick the spiral type Rail (chord) but the spiral is still entered as length and end radius.

It'd be helpful to have the option to define an alignment curve using a chord bearing input.
