Reports of pilots about any kind of inadequacies are often brought up, mostly by citing them as absent, so apparently everything is ok.

We have to get away from that concept.

Every report about any inadequacy points, voluntarily or not, to somebody to blame. In today's environment this is highly critical and not welcome.
Pilots are often discouraged to maintain such reports, for many reasons, but mainly because they would cost money or incite lawsuits. Friends working at the big one in the ME even experience open harassment if filing safety reports!

In the case of the airspeed tapes, there is basically no big surprise. Everyone know that a round display is easier to discern in stress moment than any tape. Pilots can get used to tapes, but will never perform as good as with round instruments.

However: The underlying problem with this accident is the switch between moving throttles and fixed ones. The same findings apply: Pilots can get used to fixed ones, but perform better with moving ones. The real problem is when they were trained on one and then switch to the other design. It takes a long time to get the new one under your skin, especially when moving from fixed to moving.

That is what should be addressed, because a change of any display or system will be "discouraged" by the lawyers and bean-counters, often leaving the pilots with the lesser adequate solution.
Either give pilots more training when changing, or leave them on the system they have been trained initially.
But again, this might involve cost and will therefore be decried.
