Get all rooms (Sockets) schema question

Hello!
Just a quick question about Get all rooms action:

Just testing, I have this on Socket/Connect:

On this API:

And the output is:

{
"rooms": [
"3T92Y_Xww2slBH3qAAAB",
1,
"h-5lYDYh_-xIU2bmAAAD",
"D6QpBSwRHdEbE_1XAAAG",
"gVeRcrk9Y6hGiQyIAAAH",
"xQmfqx8doen3rNEZAAAJ"
]
}

After a while

{
"rooms": [
1,
"h-5lYDYh_-xIU2bmAAAD",
"D6QpBSwRHdEbE_1XAAAG",
"gVeRcrk9Y6hGiQyIAAAH",
"xQmfqx8doen3rNEZAAAJ",
"WuoHmCTfpSk7k_tRAAAL"
]
}

And so on... It's okay to have it this way?
