These days I write a lot more song lyrics than poems, but they're basically the same.
I use https://muse.dillfrog.com/ in one tab, and any old place I can put words in another tab or window.
Eventually they all gets turned in to reStructuredText and put on my website. Or, I guess in most cases, I'm generating the reStruturedText and the lyrics are just unadorned plain-text.
I've used scripts to compile books of song lyrics, but only so I could pick a binder's worth bring to a song circle.
I've thought about publishing a chapbook with some of the lyrics. Ebooks with poetry seem like such a pain to produce, though.
Mostly, it is organizing them in to logical chapbooks that sounds like a pain. They need focused chapbooks, not just "I made this in <this> month."
With my particular process, the only thing that's more of a pain is transcribing the lyrics. My specialty is improvised lyrical acapella, so I basically pants the poem and melody at the same time with my mouth.
