HHH Hagaddah: What is the point of Ilu Keir'vanu lifeni Har Sinai, Vlo Nasan lanu es HaTorah?

In Dayeinu we have a line:

Ilu Keir'vanu lifeni Har Sinai, Vlo Nasan lanu es HaTorah - Dayyeinu?
If YOU had brought us near Har sinai but had NOT Given us the Torah - Dayyeinu?

What is the point of going to Sinai without receiving the Torah? What value is there to be at Sinai alone without even being commanded by G-d?

Hint:

1. What are the TWO Haftoros associated with the Parsha of the Asseres Hadevarim in Yisro?
2. What theme have they in common?
3. What theme do they omit?

Given that Ma'amad Har Sinai without the Torah has some significance:
Q: How is that significance manifested in Jewish Practice?

Hint: What Minhag-in-common is manifest during:

1. The Reading of Shiras Hayaom
2. The Recitation of Kiddush Levanah
3. The Reading of Asseres Hadibros

Moa'dim Lesimcha!
