Depends on the industry and specifics of a company. Are they game developers with multiple sites? Is the customer a large company with a lot of vendor relationships using different systems? Are they a vendor of some customizable component used by many large companies? Is there a good integration with their bug tracking? Do they need to long term support of 25 years? Pain was in some part of their process that was constrained, maybe technical (workflow or integrations), maybe legal.

If Git works well enough, great! If not, maybe a different system fits better[0].
