In my experience, the c library also depends on several additional libraries which is fine except it needs version 5.0+ of a library that you’re already using 3.4 of. The APIs for the library have been significantly changed, a function in the library that you heavily use has been deprecated, and upgrading to use it is more work than just implementing the desired feature yourself. The manager who suggested the library thinks you are overstating the amount of work using it will require and thinks technical debt is the money he still owes the Indian subcontractors.
Soon he’ll be streaming with an unplugged mouse and keyboard while his big brother (hired lackey) plays. Maybe we are already there.
