Okay yeah actually I'm still thinking about it and the other reason Tech actually dying here doesn't feel narratively fitting is. How many times has this series asked "what can the clones be other than soldiers?"
Is that all they are? Soldiers?
And giving Tech bits and pieces of what life can be for clones outside of being soldiers and then killing him off in a fight feels... like it's just trying to say they can't ever stop being soldiers. And that actually yes that is all they are. It feels weird. Every part of it feels weird either because it's so ambiguous or because it seems to set the narrative themes back a huge degree.
Also, the idea that Tech's sacrifice is too meaningful for him to come back... is it? He died on a mission where they obtained nothing they were looking for and went home absolutely defeated. And immediately after Omega gets captured anyway while Hemlock uses his "death" to manipulate his family.
Thematically his death doesn't move anything forward. It's very sad and well executed in the moment but it doesn't really mean anything other than that he's willing to sacrifice it all for his family, which we already knew.
His survival though, either to move him into place for the next season or just living with the consequences of his decision like some sort of permanent damage, could mean much more.
