I think one should look at it more as a ”survival” issue not as much as how much work are involved.

In the end it will likely be a survival issue considering how fast technology development moves nowadays.

Just look at all the DAWs, toonetrack type apps, stem splitter apps and more and most with very attractive GUIs and workflows. There might not be any real competitor today but suddenly one day they will be there and then it is to late to start revamp the software.
