Concern about display adhesive bond

Hi, I have an iMac 5K 2017 and I wanted to clean the inside and replace the thermal paste to maximize thermal performance.

My concern is about the display adhesive. Most people who have done a repair like that don’t have problems based on the reviews of the adhesive parts on iFixit (although we don’t know after how many hours/days/months they wrote the reviews), but some users claim that their displays come off and break down due t poor adhesive bond.

For some that happened after 1-2 days of installation and for others after 6+ months.

You can see even this guy on the video below having that problem, ended up with a broken display.

Seeing all those comments and that video, I’m very scared about doing that repair, because then I will be anxious all the time if the display will break down the next minute…

What’s your opinion about all that?

ifixit says that you have to completely remove the old adhesive and clean well the surfaces with alcohol so the new adhesive will be secured well, but again, is there a way to be sure my display will be secured and won’t come off randomly, or the reality is that you will never be sure with those types of adhesive and you have to accept that possibility of the display to break down randomly??
