Especially if you want to compute the inverse configuration to remove service instances that are no longer needed. In terms of vendor support, I'd hope that if you're paying that kind of money, you're getting a product that meets your requirements. Something that should be assessed during vendor selection and procurement. That's just my preference; do whatever works best for your use cases.

Deltas are _super_ hard. But you never need to do them. Always produce
a complete config, and let the vendor deal with the problem.

We've done this with Junos, IOSXR, EOS (compass, not arista, RIP),
SROS (MDCLI) for years

If you remove the need for deltas the whole problem becomes extremely
trivial. Fill in all the templates with data, push it.
