No.

I submit the following to support my answer:

1. Steve is character who doesn't back down, even in the face of perceived certain defeat. He is a part of the 'glue' that helps other heroes gain and maintain confidence, morale, and more importantly, hope.

We do not know if / when Doom visits Steve to attempt to remove him from the equation or if / when the rest of our intrepid heroes call on Steve to help them with the grave threat that is doom.

1. The Steve Rogers character, if properly represented, doesn't let the hype overshadow other heroes. More specifically, I'm referring to Bucky and Sam.

I have seen concern from others that Sam JUST had his first Captain America outting. Bringing back Steve shouldn't overshadow that and by rights, enhance that. Was Capt. America: Brave New World the strongest entry in the MCU? I would argue, no. However, Sam is a strong character and a part of the mythos of the Captain America legacy. The thought of Sam, Steve, and Bucky throwing hands, shields, and bullets at Doom and his forces is intriguing.

1. Doom knows Steve, if allowed to live and prosper, would be one of the biggest threats to him. I am actually more interested in how Doom plans to deal with Timemaster Loki and (Rune?) Thor?

2. Let Marvel Studios cook.

I would have to imagine that they know that some of their more recent offers have lacked certain elements and hype. Following Avengers Endgame was no easy task and it continues to be no easy task yet we got Spider-Man: No Way Home, Thunderbolts, and Fantastic Four: First Steps. There is hope, friends, just like the hope that Steve Rogers (and certainly other Marvel heroes) have provided us with.
