If no pipeline is created we currently have IID gap.
This is due to fact that we generate IID not on save,
but rather ahead of time. This results, us,
losing IIDs.

Partially addresses #47424.

This is useful since the current scheme allows us to freely delete any
records in internal_ids. If the record is not there, it will get rebuild
using the init block.

We require passing in 'init for the time being and as long as its
not expensive to do so. This makes the scheme a bit more robust.

If at some point, this is expensive - we may choose to make this
optional while losing the ability to recalculate the value on the fly.

Closes #49609.

We can extend this later, but for now we don't have the use case.
