AH HA! There are non-TXCO variants of the RAK3172. And the implementer seems like he used a variant with one integrated.

Suggesting fix:

Rename the "rak3172" folder/defines to "rak3172-t" which is the postfix that differentiates the internal TXCO/non-TXCO variant. Also adding a big warning to the variant description within the source code.
