Usually shortcuts are good for lock-in because besides being useful, they get you used to certain workflows. For example, excel has a useful shortcut where "CTRL + ;" inputs today's date, and "CTRL + SHIFT + ;" inputs the current time, which you can do in the same cell to create a date-time instantly with almost a single motion.
It was a source of endless frustration when once I was extremely used to this shortcut, I later switched to google sheets for a different project, and the shortcut didn't work the same. Google still supported both individually as they had copied excel, but the way they work on sheets is before inputting either the date or time, it would delete whatever existing value was stored in the current cell, meaning you could no longer instantly input both a date and a time to make datetimes, you instead needed two columns where before one would do.
Shortcuts increase the frequency of these kinds of friction points with your power users when they move elsewhere.
