Instead of pulling support completely, Canonical can support the applications where there is a specific need. It will work with WINE, Ubuntu Studio and gaming communities to solve the ultimate end of life on 32-bit libraries. But players must still be able to run old applications on newer versions of Ubuntu.
In a blog post, Canonical said it has been discussing whether it is internal to support 32-bit x86 since 201
Canonical warns that running software that gets a little test is inherently risky, and since there are fewer eyes on 32-bit x86 packages, there is an increased chance that they will develop bugs. Although it's a bit of a risk scenario, at least Linux users with extensive Ubuntu collections won't lose their Steam games libraries.
