Binda being compromised would hurt one of the remaining standalone women's races, so it's a double-edged sword. Sure, its position is usurped by an important and historic race, but it's a race where all of the importance and history is men's importance and history, whereas Trofeo Binda is one of the last remaining high level races where all of its history is on the women's side of the sport.
I mean, the era of the underfunded privateer race organiser consisting solely of enthusiastic unpaid amateurs scraping together enough money to hold a race at the highest level being over is in many ways a good thing, and RCS actually getting more deeply involved in supporting and protecting the Giro Donne rather than just licencing out certain graphics and trademarks likewise... but at the same time I'll be sad to see those people who kept the sport alive as a labour of love chewed up and spat out once the big organisers, whose apathy and penchant for doing as little as they could get away with helped stunt the development of women's cycling for decades, decided the time was right to step in. The Primavera Rosa even if we do an Amstel Gold and pretend it's not being set up as a new race and give it the history of the original attempt at the race dates back to 1999 and lasted seven editions (and that in an Italy which, at the time, was probably the most supportive place of all in terms of women's cycling, capitalising on Luperini's successes). The Trofeo Binda has run since the 1970s and is the oldest ongoing race on the women's WT calendar, having missed only two years in the mid 90s and the pandemic-hit 2020 edition.
I mean, look at the ages of the various WWT one-dayers here:
Strade Bianche: 2015 (8 editions)
Ronde van Drenthe: 2007 (continuous save 2020 for 15 editions, but the smaller Drenthe women's races date back to 1998)
Trofeo Alfredo Binda: 1974 (46 editions)
Classic Brugge-de Panne: 2018 (5 editions)
Gent-Wevelgem: 2012 (11 editions)
Ronde van Vlaanderen: 2004 (19 editions)
Amstel Gold Race: 2001 (3 editions, then over a decade's layoff, then five editions from 2017-present skipping 2020)
Paris-Roubaix: 2021 (2 editions)
La Flèche Wallonne: 1998 (25 editions)
Liège-Bastogne-Liège: 2017 (6 editions)
La Course (now usurped by Le Tour de France Féminine): 2014-2021 (8 editions)
Clásica San Sebastián: 2019 (2 editions)
RideLondon Classique (now usurped by stage race version): 2013-2019 (7 editions)
Pooley Plouay: 2002 (20 editions)
GP Vårgårda: 2006-2019 (14 editions)
As a result, I feel like the Trofeo deserves a bit of protection of its history and heritage as it possesses a history and tradition of its own, independent of having prestige inherent drawn from being an equivalent to a men's race, and that is becoming something almost unique on the women's calendar now.
