I don't like them on this particular jacket but on leisure jackets, overcoats or black tie they can look stunning whit the right proportion.
One drawback is that it is impossible to have sleeve length adjusted on these...
Not impossible, just limited by the amount the sleeves can be shortened by adjusting from the shoulder.
The sleeve can usually be shortened up to 1.5 inches without too much problem. As the amount to shorten increases past 1.5 inches, you will encounter more issues around the biceps area of sleeve tightening and giving a flatter appearance.
1 7/8" to 2" would be the most I would recommend, this depends on the type of cloth and your own judgement.
Seal King mentioned below, if your considering shortening the sleeves from the shoulder for jacket with checked cloths, be aware that the alignment of the stripes would be offset and out of alignment.
I found it helpful to trim the sleeve lining only half the distance the sleeve is to be shortened. For example, shorten from shoulder 1.5 inches, cut the sleeve lining .75 inches.
I have not found this in any books that I have read, I just found this a bit easier while doing these alterations.
You can see how to properly do this sleeve alteration by looking in David Carlin's book. There used to be a link found in the forum, not sure if it is still available.
Do not attempt this alteration by cutting the sleeve the same measured amount across the top!
