Internal vs External Zooming and Durability

I don't know of any studies proving the case of "L" lenses being more durable, but one would think it is true. Pro equipment in the hand of a pro is likely to get used 10x to 1000x that of an amateur taking pictures of their family. There is a lot more travel and the opportunities to bang the lens around with pro use even if they are more careful with each use.

It used to be that most L lenses used internal zooming and focus whereas the new RF-L lenses all have external zooming and focus. Most EF and RF non-L lenses are external zooming and focus. Assuming it is true that EF-L lenses are more durable, will the new externally zooming and focusing RF-L lenses be as durable?

Let me say, it seems the external zooming was done for good reasons, namely making the lenses smaller and lighter, but does it compromise durability?
