How "safe" (from a best practice and supportability perspective) is the use of DLL injection techniques?

Another question in internal discussion.

Here is one reply:

From:
Subject: RE: DLL Injection

DLL injection is never safe. You're talking about squirting code into a process that was never designed, built, or tested by the process's author, and co-opting or creating a thread to run that code. You run the risk of creating timing, synchronization, or resource issues that weren't there before or exacerbating issues that were there.

    And yet this is something some companies are forced to do every day, as a matter of practice, due to lack of extensibility in the platform. It's been happening for at least a decade.

    Do you know the reason why those companies opt to use this technique? Just curious.
