Data migration (including static/initial data) can in theory be done using BACPAC (and DACPAC and BACPAC share a file structure so you could start with an SSDT DACPAC and expand it, in theory), but the tools that work with BACPAC in general are even flakier and BACPAC was primarily designed for backups rather than data compare, which is why SSDT mostly opted out of managing BACPACs at all and stuck primarily to the DACPAC subset when outputting artifacts (and part of why DACPAC and BACPAC even have different names). (SSDT can read BACPACs pretty well as I recall, and using BACPACs in SSDT for things is still sometimes useful.)

(Plus, yeah, BACPAC doesn't solve all the other problems with DACPAC that most of the tools are still clumsy mostly closed-source things that work with Microsoft's SQL Server alone.)
