Nah, they won't...
Of course, bugs should be fixed.
But it's not correct to state that their software is "inefficient", or to expect that prioritising continuity and consistency between applications would "improve" the software. As a matter of fact, many perceived inconsistencies are unavoidable (like keyboard shortcuts), and some even intentional ! And there are indeed also inconsistencies which are just plain silly and stupid (like a dozen designs for a chain icon for entering equal values).

In the long run, it's better to let versions of applications gradually change in several (hopefully) useful directions. E.g. were in the middle of a transition in the general interface of many Adobe applications: from dozens of floating windows to a consolidated Properties panel. In the early days of Adobe tools, users didn't like dynamic and content-sensitive panels, but we've got used to them over time. In new applications (like Adobe XD and Dimension) this Properties panel is the main thing ! In older applications Adobe tries to move very slowly with it, in order not to disturb users their routine too much...

These changes don't happen overnight, and they don't always work out well at first. But it's important for any company in this area to move on ! And while moving, you make choices and mistakes.

However, because of the speed in which a company must or tries to move, users are often confronted with less-tried-and-tested new versions, with an increasing number of bugs. You're right in requiring that development should deliver more robust tools, but the trendy Agile Manifesto leaves ample room for trial and error...
