Perhaps the old reasons will do just as well. Hokkien is an interesting case of being involved in a potentially fractious political situation- one can imagine to further distinguish themselves from the Chinese mainland, the people of Taiwan promote the use of Hokkien. Not dissimilar to say bilingual laws in Canada.

After all, the nineteenth century saw the consolidation of national languages and elimination of regional dialects in the name of fostering nationalism, which continued in the twentieth but also saw the revival of languages like Irish or Hebrew for new nationalisms.

I doubt that desire for cultural differentiation is going to change much about the diglossic situation in Taiwan, since the continued use of Traditional Chinese characters is already a pretty big differentiator. The government is making some effort to promote the Tai-lô writing system (e.g. https://tailo.moe.edu.tw/index.php ), but overall there's very little incentive for Hokkien speakers to become literate in it. If you look at Wikipedia visits from Taiwan, 92% go to the Mandarin version, 6% to English, 1% to Japanese, and Hokkien is in the tail of small languages behind even Cantonese and Classical Chinese. Of these, I think English is most likely to grow in the future.

Also, the differentiation potential is somewhat limited due to the fact that the majority of Hokkien speakers lives in Fujian province on the mainland (Hokkien = Fujian) and there's some preservation work going on there as well. E.g. Xiamen University's Speech Lab had a working demo of spoken-Hokkien-to-written-Mandarin translation in 2018, although the link shortener they used has since suffered from link rot. https://speech.xmu.edu.cn/2018/1215/c18169a359542/page.htm

You’re not wrong, not to mention the problematic nature of conflating Hokkien with “Taiwanese” identity, as that then omits the Hakka, never mind the aboriginal languages. But one could see a Benshengren revival of Taigi nonetheless, even if only as a set of quixotic pan-Green government initiatives.

Also, Hokkien interest is present even outside of that geopolitical flashpoint:
