I am fairly certain that licensing is why PHP does not have native support for PDF. I do not know for sure why fpdf has become legacy, my guess would be licensing issues as well since work on it really slowed when Adobe started cracking down on infringement. Once again, this is all speculation since I am not an Adobe insider.
I still use fpdf for projects that I control the markup, and it does just fine. It is the new and changing web standards that create an issue for me, so if I have clients on shared hosting that want up to date conversion, I will use my class with the pdfLayer API. If they can afford $5K to $7K annually, there are other libraries out there.
These prices are all high because of the high licensing charged by Adobe.
