The way OcSetNvramVariable works is that it attempts to read the variable. Block can be used to delete the variable first in order to always force the Add value instead.
I propose a third option. Why is this useful? Consider the following use case: We need some base set of boot-args to boot up OSX. So we add them with Add.
Okay, so what if we just don't put boot-args into the config. That works, except if we require certain boot-args to boot, then forgetting to append them will make the system unbootable even more painful if the vault is used. So ideally, we can use OC's "erase nvram" option to wipe all the variables and then reset them with a clean default. A second use case: csr-active-config is used for SIP. OSX does the checks to make sure csr-active-config is only modified in recovery OS.
However, setting it in recovery OS still doesn't work if there is already an Add entry. Given the above, I do not see an issue or the need to change anything. The logic looks perfectly natural to me.

On the other hand, I don't see a good point for the specified behaviour either except as some sort of request sanitizing, imo wait for what osy86 has to report later. In this case I do not mind ignoring the spec and incorporating the following change in SetVariable wrapper of FwRuntimeServices.Press question mark to learn the rest of the keyboard shortcuts.
