Because Coronation Street is a tired old soap and how both Coronation Street and EastEnders were both lucky to last a decade on TV where EastEnders lost its credibility altogether since 2013 and the worst British soap out of the 4, when Coronation Street won against EastEnders at the soap awards in 2013 and how EastEnders has had a lot of farfetched retconned storylines and characters backstories altered, and how Emmerdale Farm evolved into Emmerdale, again all 4 of the main British soaps aren't what they once were, and so it's at the stage now where the best British soap is Hollyoaks due to format/structure whereby it reduced the number of episodes back to 2-3 episodes per week and have evolved over time with a more diverse range of older characters and not like how it was when it first began in the 1990s and has now been going well over 30 years.
With Coronation Street's termination/conclusion/end eventually in time, it would need a slight revamp into the next decade and beyond, with the soap being targeted towards an adolescent and young adult audience but eventually broadening its appeal to teenagers like how Hollyoaks originally was in the 1990s until around the 2010s, ultimately with a cast of 15 characters instead of over 38, the longest-serving actor obviously being William Roache, who portrayed Ken Barlow since the first episode.
The exterior of the pub in Coronation Street should be repainted over a 7 year period to Red and Gold/Brown and Cream or vice versa, like the pub in EastEnders, which would either be a brief shift to a brown/red tone and then the relaunch look representing a classic old Manchester pub. The pub would have the look of a traditional smooth and silky pub/boozer that could fit into any era also whether present or past.
