Why did the UFP use phase cloak device during the Dominion war

[Jason 27]

I can think three possible.

One risk using like talk Star Trek TNG

2 Romulus made big deal out of it.

3. Section 31 was already using way hiding UFP had the technology some other agency like them.

First it risky all fairness a computer  could done the job far as the risk go. Question why world it done that way might will had do Section 31 aim start war the Romulus. Let face the Klingon Empire and the Romulus star Empire each other throats. Section 31 motive to did something like that in Star Trek into darkness.

2. Romulus would made big deal out of it. This interest idea few problem first Romulus Star Empire for what worth was worry about the Dominion. Did favor a Dominion victory just want dust settle to lefting stand or best chance of being left standing.Head Tal Shair spying for the UFP show just how at least that agency felt.Provide intelligence short after a least the Romulus Star Empire sign none aggressive pack. 

3. Section 31 already using this seem make the most sense. No reason assume for second the cloak device technology made more advance was not being used time TNG. Even discovery the Romulus Star Empire next no real response. Possible because the Romulus Star Empire pure the UFP fleet equal cloak device rather just smell branch of starfleet.;

They mentioned why the Federation doesn't use it. They have a treaty with the Romulans. That may seem like "So what? Just do what you want." Except, the Federation is trying to avoid an all out war with the Romulans. Take a look at our modern day. The nuclear arms treaties we had with the Soviet Union. The US and the USSR didn't just ignore those because the consequences would have been disastrous. It's the same thing with the Federation and the the Romulans.
