I had the same thought.

The “inertial hump,” the learning curve, is going to be like 30 minutes, if you take 15 of those minutes to eat a sandwich.

If you want to reduce it even more, do this:

1. Install new tool.

2. In your .bashrc define some flag combinations that make it even more like your use of old tool, with similar-sounding aliases or even ones commonly used for old tool.

3. Now in the unlikely scenario that new tool goes away, you’ll still be current w old tool from those lookalike commands.
