In thinking about the syntax, with both seal and freeze as the variations, it's worth thinking about aesthetic precedence.
For example, {# obj #} might seem less aesthetically pleasing to most than {| obj |} (while this is subjective, there's likely a rough average towards the latter due to greater shape congruence between the different symbols in this case).
For this reason, and with these examples, I would suggest that freeze should be the priority aesthetic. For the reason that the guarantees of freezing provide the most useful correctness and security guarantees.
So effectively I would be suggesting with the current syntax that they should be swapped around in meaning - {| |} for freeze, and {# #} for seal.
