Is your request related to a specific problem you're having?

Aliases are useful for example to support GitHub’s names, and map them to highlightjs names.

The solution you'd prefer / feature you'd like to see added...

Such as like so: https://github.com/wooorm/lowlight#lowregisteraliasname-alias, but anything that allows mapping a new label to an (existing) language name.

Any alternative solutions you considered...

There is no access to languages or aliases, so it’s not possible to do this in userland.
