It's a fair point. Most of our customers work with CPP, C# and Java in enterprise / back office contexts, which is why no PHP or Javascript right now - we've been tied up with other priorities. That said we just added Python to our main SDK and PHP is coming.
I would think that JS/TS support would be relatively high up... my own bias speaking, but a lot of development and effort to easing cloud apps is JS/TS centric.
I work in a FAANG on stuff that is definitely "enterprise software", a major part of what we develop is written in TypeScript.
I admit PHP will not be as good of a candidate but for smaller companies it is still extremely attractive, and it's probably easier to develop since you can write PHP extension in C.
Plus our enterprise automation product can basically talk to anything via REST API ( https://www.pdf-tools.com/docs/conversion-service/api/conver... ).
But yeah - now you got me fired up to annoy some colleagues ;)
