what is the case against daisy chaining fixtures?

Consulting engineer here. Been in the business since 2000 and every design firm I've worked at has "daisy chaining of fixtures not allowed" in the spec. I had assumed the reasoning was that interruption of one fixture would kill power to downstream fixtures though since fixtures should not be worked on live anyway this is less of an issue. Reading through this forum I wonder if back in the day daisy chaining was easy to get wrong / not a given it would be done legally if you didn't have a strong grasp of what was required. But now between code and manufacturing practices it is basically hard to do it wrong? As the engineer I'm not in tune to the means and methods of fixture whips and connectors and whatnot.

The context for me is in brick and mortar construction - schools, courts, hospitals, government facility office spaces... (not industrial, residential).

I consider this an opportunity to reexamine why we have we been doing things this way in the first place, and does it still make sense? Is daisy chaining a legacy best practice that no longer makes sense, or are there still good reasons for prohibiting it? I would appreciate your collective wisdom here!
