I myself don’t know the answer to the above question
Adiyen

Srimathe Rangaramanuja Mahadesikaya Namaha

That’s okay Adiyen.
The phala Sruthi of this song indicates

“sivaloka mavaapnoti”

Meaning Kailasa. If you remember Adiyen would have told maha periyava would have referenced “Kailasa”.

According to Veda, SriVaikuntam has “Na cha Punar Avarthathey”

Meaning “A place of no return” or “The one who goes inside does not come back”

Kailasa does not have that qualification with due respects. AFAIK it doesn’t.

Now what about praising one as ParamathmA etc? Anybody can praise anyone as they want nobody can stop it.

தேவும் எப் பொருளும் படைக்கப்,*
பூவில் நான்முகனைப் படைத்த,*

தேவன் எம் பெருமானுக்கு அல்லால்,*
பூவும் பூசனையும் தகுமே.

English Translation

My Lord created Brahma on his lotus navel, who in turn created the gods and beings of the worlds. Other than my Krishna, is there any Lord worthy of worship with flowers?
