You're looking at it all wrong. The issue isn't Amy, it's what they did to Tails.
The meta era turned him into an insecure Sally Acorn clone who just sits in a workshop building gadgets. He lost the adventurous spirit he had in the old games. He's not the kid who was inspired to be a hero like Sonic anymore.
That's where Amy comes in. You say she's pushy and an "uptight and overly-romantic type". Good. That's exactly what Tails needs. He needs someone to drag him out of the lab and back into the action. Her whole deal in SA1 was becoming a hero in her own right, craving thrills. She wouldn't put up with him just sitting on the sidelines.
It's not about her "giving up" on Sonic. It's about her finding a partner for the adventure she wants, and in doing so, she'd accidentally fix Tails' character decay. It would force him to grow a spine and be a hero again instead of just being Sonic's glorified tech support.
The dynamic itself has potential. It would course correct Tails back to being an adventurer, not the watered-down nerd he's become.
