Just as random person watching a film, there are some things about Luke in the OT that resonate with me:

• He is hopeful and idealistic.
• He is a good friend. They save him, and he saves them in turn.
• He triumphs not with strength or violence but with compassion.

He is even willing to rebel against the advice of his mentors in order to follow his heart and stay true to his ideals. The relationship between Luke and Anakin is the lynchpin of the whole series.

In the PT, the Jedi are unquestionably flawed and - once you sit back and consider it - their philosophy is pretty awful (and ultimately leads to their own destruction):

• They recruit children and indoctrinate them, turning away candidates who are old enough to have life experience that might 'interfere' with their 'training'.
• They steal Anakin from his life on Tatooine but leave his mother a slave.
• Yoda basically tells Anakin to let his mother die, when Anakin's dreams could easily be a warning from the Force itself.

Quibbling about the specifics of what 'attachment' means isn't super relevant, IMO. It's clear from what's on screen that Luke's outlook in the OT and the outlook of the Jedi Order at the time of the PT are completely different.

Luke is not a member of the PT Jedi Order, and is a much more sympathetic and better character for it. The PT Jedi wouldn't have taken him anyway, had they had a choice. He's too old, too 'attached'. If Luke had listened to Yoda and Obi-Wan then Anakin would have either killed his son, or Luke would have killed his father, and I reckon the galaxy would now be under the rule of Darth Luke.

For this new version of Luke to present a child with the choice of whether or not to ever see his family again doesn't feel compassionate or hopeful. It honestly feels just as abusive as the Jedi Council telling Anakin he was too old and loved his mother too much. At least when Yoda told Luke to abandon his friends, Luke was an adult.

From what I've seen in the movies, the old Jedi were pretty much a cult, and if Luke is going to dogmatically follow their teachings on attachment now then he's just continuing a cycle of abuse. And TLJ showed us exactly where that cycle ends up.

To give the fandom Luke back for five minutes and then have him mentally torture a child with this 'choice' seems like the biggest bait-and-switch ever. Or maybe it wasn't, because having Luke just take Grogu from his father and leave in the first place was pretty iffy.

It's pretty clear that the people writing Luke now have a very different idea of the character than a lot of fans do.
