I've long advocated for this. Subscription based services are the norm and season tickets, seems rather analogue by comparison.
People's sensitivity to cost varies. From my point of view, because I live a 3hr drive away, and can't attend every home game. Cost isn't the main impediment I'd be happy to pay the full season ticket price for a hybrid ticket.
For, say £50-80 per month, If I could watch streamed content, games from the club, with the option to attend an agreed amount of games as and when, by selecting a seat in advance (subject to availability). I'd see that as value for money.
