Splash Text Size Unchangeable in Resource Packs

In adding a splash.json, I found quickly that typing too many words makes the text exponentially harder to read. Despite a full-size monitor, the only thing I can do to improve legibility is to change UI size to -1 (which itself seems odd…) after toiling over some code lines I found in the main menu .json (had the word "art" in the title) for a few hours, I discovered that there is no way to increase the size of the splash text. There's a "size" parameter & some other parameter with nonintuitive values (e.g, 87%, 20, 27%x, ordered randomly), but they only seem to affect the splash's position on the screen (despite already having that defined earlier in the .json as "top-right" or something similar).

It's great that the splashes are tweaked in position to match the user's platform, but there seems to be redundant & unintuitive parameters that end up making the main menu a mess to modify. The Minecraft logo is easy enough to change (make the "size" a bigger number), but the splashes depend on a splash generator function & it looks really bad when I try to change the code. I hope the splash implementation & other features become more user-friendly for addon creators to improve the overall qualify of the game (such as correcting the hotbar being off-center).

Perhaps later I'll clear up this report & make it more concise (including the relevant .jsons & workaround).
