It doesn't matter: the equation is exactly the same. Why would you hire someone to work on a bug fix or security fix when you could hire that same person and have them work on something even more valuable again?
When framed correctly (there's effectively an unlimited labour supply for most companies, and effectively a limited demand for staff) then the question becomes "shall we hire an engineer to fix security bugs when we don't need an engineer for anything else?".
In effect, there is, yes. At the very least, there’s more high value work that most companies can do than there are engineers to do said work. There’s a reason literally every leadership course teaches you how to say “no” over and over again.
