Maybe it doesnt offer it to 1909 clean installs, while it does for upgrades?

Possible.

Disk 0 is now the selected disk.

Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Recovery 499 MB 1024 KB
Partition 2 System 100 MB 500 MB
Partition 3 Reserved 16 MB 600 MB
Partition 4 Primary 837 GB 616 MB
Partition 5 Recovery 563 MB 837 GB

There is potentially a confusion with nomenclature, especially around the words 'reserved' and 'recovery'.

Of course I have an EFI system partition - that is not the same as the 'System Reserved Partition'. However, on UEFI systems, It seems to have taken over the boot manager/BCD duties from the System RP, but not the WinRE environment.

That little 16 MB Reserved partition is the 'Microsoft Reserved Partition' (vs. the System RP). I have that on my system. It has no recognizable filesystem, and seems to be just raw 'scratch space'.

I have no Recovery partition, which, judging from the name and size is maybe doing the WinRE duties from the System RP of old? As you have seen from my reagentc output above, I have no WinRE environment.

So yes, I see what you mean about several 'reserved' partitions. But different from the 'System Reserved Partition' of old.

Anyway, I made a chunk of unallocated space, and did a clean install to it, and no System Reserved Volume was created. And from this clean install, the same thing happened: The CU installed fine, I rebooted, checked for updates again, and this Security Update failed.

I give up.

Give up, what and why? You wrote: "I do not have a separate System Reserved partition - never have."

EFI, WINRE, RESERVED, RECOVERY whatever, all of these are System created AND System Reserved Partitions.
You have no recovery partition hence you have no active WinRE environment. WinRE can also run off the Primary System Volume (drive C:) if configured in such a way. How did you install WIN10 initially?

I give up on trying to install this Security Update.

Again, there used to be one thing that was actually called the 'System Reserved Partition'. These other system partitions are indeed reserved, but are not THE System Reserved Partition, which is what the error message refers to.

I installed originally by a clean install from USB installer to a pre-existing partition.

This "USB installer" was it created by the Windows Media Creation Tool?

In any case you probably need to go through an in place upgrade, this will rectify your issue and also re-create the default partitions for specifics such as WinRE. It shall not take very long.

I will give it a try (in place upgrade) a bit later. Thanks for the suggestion - for some reason I hadn't thought of that.

Did you check the list of all installed updates once your OS got updated and restarted? This update has only shown up itself there and then.
