Ok, why not say they have to do all these things now and then show good behaviour for 2 years and we can come back and evaluate the application? There was no law that they needed to join immediately.
Sure, thats what I mean by precondition stringency + toughness. i.e not a mechanism (available within NATO) per se, but definitely a clause that TR sticks to at least for the two new entrants where it could do so if it wanted to (compared to those that are doing the same but already NATO members).
There has obviously been some kind of actual reluctance to do that (in TR executive branch) past the words/statements etc and/or caving to pressure applied.
You will notice in the word document that Sweden and Finland also do not own up to having provided any support/harbour to PKK/YPG....just that they "commit to" not doing so (like they say they are already doing, and onus is on TR to prove in court process that they are not).
When it comes to any legal case in these two countries, TR or plaintiff it elects will have to show, prove and get conviction that the defendant as being PKK/YPG (and then the respective countries official apparatus elements being involved in such, which would likely need an international court past that).
There is lot of legal cover and legalese that makes this hard (or it would have already been done since PKK at least is already proscribed as terror group by EU framework).
That is already current legal framework and process in existence that TR has to meander through to try get concrete results, nothing more has been added or taken away.
Given this wordology and reality (beyond the words)......simple tough precondition for TR to adjudge on for itself would have been the strongest prudent option from the Turkish interest perspective....and like you say not cave into some urgency for anothers NATO membership (given bilateral security arrangements they can make in interim more than fulfill that void anyway).
If it hasn't been done, that is something Turkish population should look into and hold their elected officials accountable.
