Thanks for the suggestion. I'm not against including the feature, but there are a few things to consider:
Is there enough demand to justify the increased maintenance and code complexity (I don't use it myself [yet])?
How well do the currently supported symbols map to the typed ones (I assume they use the same/similar symbol)?
How well does the automatic mapping between commands work?
I'll try to investigate some of these as soon as I have more time, though it may take a while.
Add a mode for typst, a new open source typesetting system. Similar to https://github.com/QuarticCat/detypify
