Opinions on a "Vote: Timer Reset" for DF parties on the cusp of a clear?

[Saviorlito]

You do two attempts see it won't happen and hit vote abandon which is what usually happens in DF groups.

The only difference is you now have 5 people from the previous party who have been further into the fight than they originally started. There could be an option to join in progress and join extended, which left unchecked would ensure that you don't join an extended trial. It wouldn't be any different than choosing to join in progress and getting into a group that has 20 minutes left on the initial timer. Actually, there would be a difference. The people remaining in the group have knowledge of the fight and are willing to carry on. The same exact thing they would have to do if someone left with 20 minutes on the initial timer and new people joined. Literally nothing changes other than having the benefit of 5 people in the instance who know the fight well enough to carry on. The option to choose to join extended could have a pop up once checked, explaining that this is for people who are at least familiar with the fight etc etc. This would also raise the skill level of the extended trials by replacing members who do not wish to continue any further with members who are somewhat versed in the fight and are going for a clear.

EDIT: The PF system is not perfect on low population servers.
