Chopin - A Unique Legacy

Frederick Chopin, that third member of the great Polish Triumvirate (Paderewski and Artur Rubinstein the other two), was indeed unique, in that every composition he created included the piano. Even the songs written early had, of course, piano accompaniment.
What strikes me is that because of the history-shattering precedent of writing exclusively for the piano during his all-too-brief life cycle, the one apparent price that this genius paid was his inherently weak sense of orchestration.
In his great first concerto (all of seventeen when he began writing it), let alone the other works for piano and orchestra, I have come to the conclusion that these are not concerti, but sonatas for piano with orchestral accompaniment.
I as well have the same reaction to his 'cello sonata, which pretty much turns out to be a piano sonata with 'cello obbligato.
Please understand that this is not a criticism; merely an observation.
Chopin's entire world swirled around the need to probe the potential of the piano, and this he did with such brilliance and prescience that one can forgive other aspects of his writing that were, out of elemental priority, secondary.
As Schumann wrote in his journal, "Hats off, gentlemen - a genius!"
