I suppose it's one way of increasing immersion. A few years ago, I resolved that, unless my life plans changed significantly, I would never be fluent enough in a second language to be really comfortable in a conversation. Reading and writing, however, may be more accessible. There's a lot of French literature I may one day be able to access without having perfect pronunciation.
There's also the internet. Several years ago, I used to play Runescape on European servers so I could talk to people in broken French. Internet forums also have a fair diversity of language, the most popular 'French' phrases among many being "hon hon hon" and "omelette du fromage." Recently, many of my online encounters with French have been research papers from Francophone African countries where insects are eaten. In these cases, I can understand the titles and some key words, but usually end up just looking at the figures.
In any case, I suppose I am now resolved that, while I may never carry out a smooth conversation in French, learning how to read and write second languages may have plenty benefits of its own.
