Why do some people just make kiddush inside the Sukkah but eat their meal in their house?

Topic: Bracha of Shechiyanu on Shemini Atzeres

Questions:

Why didn’t the gemara also list that the Aravah is not taken on Shemini Atzeres?

See שפת אמת “שהרי חלוק for an explanation

https://hebrewbooks.org/pdfpager.aspx?req=14522&st=&pgnum=208

The Gemara asks why don’t we recite the bracha of Shechiyanu on the Yom tov of Seventh day of Pesach as it is different from the first day of Pesach in regards to the requirement to eat matzah. 

Based on the above difference Shechiyanu should be said on the first day of chol hamoed? 

See שפת אמת “אי הכי for an explanation

Question:

Is there a difference between the multiple explanations of the Amoraim as to why Shechiyanu is recited on Shemini Atzeres but not on the seventh day of Pesach?
