Fair enough. But perhaps we could both agree that the romantic style of conducting has become increasingly limited to, well, romantic era music.
It used to be that almost everything sounded romantic, whether it was Bach's Mass in B Minor by Richter, or even late Shostakovitch works. That was how musicians played and conductors conducted in the middle of the 20th century, with a few exceptions.
Now, you're more likely to hear an austere, quick-paced Bach, even if there may be trend back towards capturing the emotional highs of something like B-Moll Mass (a la Johnathan Cohen last year), but even composers I consider to be neo-romantic like Sibelius are often played in a more austere and 'modern' way rather than the overtly romantic style he himself may have actually approved of, largely.
So I suppose rather than saying that I sense a waning interest in the romantic period, I would just say that people who love the romantic period, don't mind it played in a romantic style, but pretty much every other period and genre are no longer played in the older romantic style that went crazy with the layers and layers of strings using long and intense vibratos, where conductors often slowed things down to increase the dramatic effect, etc...
In this sense, you hear a lot of composers are minimizing the excesses of the past, even with for instance, Riccardo Chailly's award winning Brahms symphonies of 2013 being great for their speed, clarity, and controlled emotional temper. It seems that the critics felt the need to applaud the updated style here, probably to encourage more of this.
