    Any conceivable way to force this bloom to render at any distance for at least one pixel to avoid these gaps?

    I don't think the bloom is the issue here.
    It's a screen space effect so no matter the distance, it will render depending on the intensity of the object.
    From what I see in your screenshot, when the lines are far from the camera, they are so thin that the aliasing kicks in and they are gaps in the line rendering, not the bloom.
    IDK how you did those lines, but you may want to find a solution to render them anti-aliased, maybe by using some alpha blending shader.

    It's a trail renderer with an HDRP Lit shader. I'll play around with other configurations and see what I can do. Thanks for the guidance.
