Another data point, got another of these yesterday at around 12:30pm, offering me 41€ to bring forward my trip by a day (Saturday morning to Friday afternoon).

I considered this for a while and after taking a half day at work, tried to accept it this morning (since the suggested Friday flight would've had me on the widebody), but alas:
