not sure about making this optional. Even if this is a dummy, it would be good to spell it out.
Using `std::optional` here is just making code more complex, adding two lines of code in one place to save one line of code in another place.
Also, it may be better to call mention *output* script in the name.

Not sure if this will always be the case, but it is currently possible to create an sqlite wallet with no name with `bitcoin-cli -regtest createwallet ""`.

In production this is always a dummy. `CreateNewBlock()` sets the script to `OP_TRUE` and then the `getblocktemplate` RPC omits the whole coinbase transaction.
It's not safe for the caller to set an _arbitrary_ dummy, because IIUC if it's larger than `coinbase_max_additional_weight` the `TestBlockValidity` internal check for `getblocktemplate` will spuriously fail. Which is why I think it's better for `CreateNewBlock` to decide what the dummy should be.

I am not sure that running tests in a loop until they pass is a good approach. Generally, when there is an issue, it should be addressed, instead of being silently hidden.

Maybe a follow-up can do this? The goal of this pull request is to unbreak OSS-Fuzz (not sure if any other deployment is affected) by simply restoring what has been done for all previous releases in the unit tests.

This seems backwards? Fuzz engines will generally prefer smaller fuzz inputs over larger ones, given identical coverage metrics. Optimizing for the worst case, which will likely never happen, and possibly pessimising the happy case reads odd.
Either this has no effect at all on the fuzz target anyway, in which case the code reads odd, or this is actually pessimising.

I'm confused, this is printing `Script verification uses 15 additional threads` for both master and this commit when I provide `-par=16`. As far as I can tell the logic as applied is:
```
worker_threads_num = script_threads - 1;
worker_threads_num = std::clamp(worker_threads_num, 0 , 15);
```
Which should be equivalent?

Yeah, never mind. The subtraction happens before the clamping, not after as I wrote above. So the behavior remains the same.
I guess I'm a bit sleepy today.. sorry.

Are you saying this will affect fuzzing behavior? Does it look under the hood to check how many items to create? I wasn't aware of that and find it odd.
What value do you recommend here instead of the worst case?
