Is Al-Albani’s writing “Sahih” after a Hadith from Bukhari or Muslim considered a detraction from the Two Sahihs, implying the existence of non-Sahih Ahadith within them, and what is the wisdom behind his doing so?

The Muslim community has accepted the two Sahihs of Al-Bukhari and Muslim with reception. Sheikh Al-Albani's statement in some of his investigations, that a certain hadith in Al-Bukhari is sound, is not considered a denigration of the two Sahihs, because he rules on all hadiths in his books, whether they are in Al-Bukhari and Muslim or other collections. A Muslim should think well of past scholars, pray for mercy upon them, and seek forgiveness for them.
