LGTM! 🎉

I've checked the repo with the following regex \.CustomRecords.*\d and couldn't find any other occurences apart from this one:

taproot-assets/itest/channels_test.go

Lines 38 to 42 in 4d9c148

	require.Len(t.t, encodeResp.CustomRecords, 1)
	var rfqIdType rfqmsg.HtlcRfqIDType
	rfqIdTlvTypeNumber := uint64(rfqIdType.TypeVal())
	require.Len(t.t, encodeResp.CustomRecords[rfqIdTlvTypeNumber], 32)

That one already checks on the custom record type, so that won't be a problem.
