The iPhone mini unfortunately was not successful sales-wise. As such, it's unlikely Apple would want to revist that particular form factor if there is simply not enough market demand for it.
I know there are fervient supporters of the size, but unforatunately, there aren't enough for it to make financial sense for Apple.

The end of the iPhone Mini comes down to one factor: Demand, or lack thereof. The first signs of trouble arose in early 2021, when Consumer Intelligence Research Partners revealed that during the iPhone 12 launch window, the Mini accounted for just six percent of sales across the new line. Later that month, a leaked Morgan Stanley investment note revealed that Apple planned to cut iPhone 12 Mini production by two million units to increase iPhone 12 Pro production capacity. Several weeks after that, a Nikkei Asia report pegged Apple at cutting Mini production 70 percent from original plans for the first half of 2022. Just six months in, the experiment was a failure, but Apple's lead times are long enough that there'd still be an iPhone 13 Mini. Sure enough, another CIRP report soon showed it was selling even worse than its predecessor did.
This is not to say there will never again be an iPhone Mini, but unless it makes financial sense for Apple, don't expect one any time soon.
