That is correct. I hope they add that feature in the future. I think the point of the wallet... was to onboard people to lightning in the least painful, but non-custodial way possible.

It is possible to accept on-chain on the wallet... but the developers have stated the Wallet is designed for lightning mostly..

Edit: I hope that most/all BTMs will use Lightning in the future. As fees rise it's logical that they all will to reduce fees and get quick payouts, liquidty, balanced channels etc.
