Sure, but it's one of the biggest go/no-go reasons. Preexisting codebase, available libraries suitable to the problem domain, platform limitations, desire to obfuscate code, developer experience, desire for speed of development, and whatever else I'm forgetting would be other reasons to choose a particular set of technologies. But the comment I was responding to was about performance implications, and whether or not development was "close to the metal", so my response was too (using C++ and Python as examples of lower-abstraction and higher-abstraction languages).
