Dropped initial ideas

[ergl]

I'm wondering what's the best way to handle initials, especially dropped initials. For raised initials, I'm basically doing the following, which works "fine":

(q
    (q [(font-size-adjust "300%")] "L")
    (q "orem ipsum dolor sit amet, consectetur adipiscing elit. Mauris semper augue vel ligula convallis, ..."))

For dropped initials, I thought of using the above, combined with font-baseline-shift. The problem with that is that the following text has to reflow accordingly. Looking at mbutterick/quad#37 I see that baseline shift is intended for sub/superscript text, and not this. I wonder if you have any ideas of how this could be supported.
