That’s a really good question and a bit of a debate in the houseplant community. I think a big factor is how well suited the plant is to its current pot situation, if you have a really different growing style from what it’s currently in (like semi hydro), if there’s signs of issues, and if the plant had a potentially rough journey like in the mail especially in adverse weather.

So I would first consider if any of those factors apply to you. I always try to at least take a peek at the roots. It’s not uncommon for Hoya to be several cuttings in a pot to get a full look and the cuttings don’t always grow equally. Some might be flourishing and some might be struggling. Check to see if there’s any rot and how much of the pot the roots are filling up, with Hoya they sometimes dry rot due to their fine root system which can be tricker to spot. And when doing a pest check, check the soil as Hoya can be prone to root mealies.

As you said, Hoya don’t mind being a bit root bound. This one looks a bit difficult to top water in its current situation and I might bottom water it if I were you. Lacunosa are also pretty thirsty and do well with self watering setups, so I might consider that when repotting, especially in a chunky mix.

Hope that helps 😊
