Does setting up Mercer Safehouse as a settlement effect anything?

I just completed the Railroad quest to set up Mercer Safehouse as requested by PAM, but I am hesitant to send settlers or place a recruitment beacon there. Is it okay to have settlers settle it or does its covert function mean that I should just leave it empty?

In other words, are there any reasons that I should leave Mercer Safehouse uninhabited (such as penalties or being locked out of quests) or can I go ahead and send some settlers over?

Solution 1:

Based on the Mercer Safehouse page at Nukapedia, and on my own hazy recollection, I think you can go ahead and use it like a normal settlement.

That page says that

The location you get sent to is random, and in the event you have cleared every settlement, it will send you to one already under your control.

Kalina has pointed out that there is at least one quest related to the Mercer Safehouse: Concierge. However, there's no reason to think that having other settlers there would negatively impact this quest.
