Not sure I wholly understand what you are saying.
But there is nothing in play at the moment that restricts deleting or editting in the way you describe in either portal and I don’t see how the restrictions you mention would be that beneficial tbh. Most people have common sense around what they delete or not as far as I can see. Atm editting and deleting is just more time-consuming in the identification portal than elsewhere (the place where ideally it would be the least time-consuming ).
For me, as an identifier it’s also not so often I revisit an observation through the identification portal as you seem to describe. If I come back to observations down the line ( e.g. because someone has commented on my ID ) … it will almost always be through clicking a notification - which will take me to the observation portal from where I can delete or comment without having it trigger a new tab. Any deleting or commenting I do within the identification portal is almost always performed immediately.
Are you saying you are against parity between these two spaces?
I also wouldn’t agree with the solution to the issue you mention ( if it is even an issue, which I’m not convinced of! ). But I think a less limiting way to deal with a potential lack of clarity in a timeline would just be to keep the edits accessible, in the same way the edits on forum comments are saved and can be seen. Anyhow - this is quite a different thing to debate imo.
