ISPs are facing ever growing costs to continue providing IPv4 services. Could you please be more specific about which costs you are referring to?
It's not like IP transit providers care if they deliver IPv4 or IPv6 bits to you.
Have you priced blocks of IPv4 addresses lately? IPv4 address blocks have a fixed one-time cost, not an ongoing $X/month cost.

How, exactly, would you propose a company recoup the cost? There are many options, depending on the commercial relationship between ISP and customer.
The ISP may simply charge a single one-time fee per IPv4.
The customer may choose to bring their own IPv4 blocks as many BGP customers do.
The ISP may chose not to charge separately per IPv4, as having those IPs enables them to charge $Y/month for Internet service.
And so on and so forth.
Furthermore IPv4 addresses do not wear out. IPs can be reused upon customer churn and excess blocks can be sold, if need be.

A growing number of providers are charging $x/IPv4 address/month as a way to recoup that cost. I expect that trend will continue. While it may (MAY[1]) be a one-time fixed costs to the provider, it’s not likely to stay that way for the customers going forward. Owen [1] Modulo RIR fees and the possibility that due to capital constraints, said ISP may have chosen to lease addresses rather than purchase them.
