In my experience, it is not an issue. I turn the oven on when I want to start cooking and only then start gathering the items. By the time I want to stick something in the oven, it is already hot. Doesn’t work with frozen pizza tho

If you don’t have an oven with a fan/convection, then sure, get an additional appliance.

You can make stews, soups and other things one would use a slow cooker for by taking a stainless steel or some other not-made-of-plastic pot and sticking it in the oven

Rant about kitchen appliances:

People should learn to use the things they most probably already have in their kitchen.

1. slow cooker is just a tiny pot shaped low temperature oven with a timer

2. Air fryer is a tiny oven with a fan

Why do people get so hyped about a smaller and more limited version of the thing they already have? Just use your oven which most likely already has all these features. I haven’t seen an electric oven without a fan or without a timer in my lifetime

Ah, yes, lets generate more needless waste
