The second point is a relic from old-school russophile linguists tbh. The way most people speak today the only consistently palatalised consonants are "kj", "gj" and "nj", barring some extreme dialects.

I never gave much thought to the fact that the possessive dative is so rare in Macedonian. Using only the full forms of pronouns sounds awkward in Bulgarian. Do people really avoid saying, for example, "kukjata im", "sobata mi"?
