This! I have two fruit trees, an espaliered Asian Pear, and an Italian Prune Plum which are planted in very poor soil. I'm pretty much on compacted glacial till, and I grow rocks like they're a cash crop. At first, I had to dig out rocks and replace the rocks with dead wood to act like sponges and hold moisture, and I would mulch, but I would still have to irrigate deeply every 2 weeks or so, for fear of loosing them.
Now at most I water deeply (light flow for at least 12 hours) about every 6 weeks if we're in a really bad drought. I watch for signs of stress - trees will tell me once I get to know them. By watering really deeply, it encourages the roots to reach deep for that water. Better soil has allowed me to grow companion plants - comfrey to the north, Iris to the south. The comfrey can be chopped and dropped to add some surface moisture.
I also accept that my fruit will be smaller than Industrially farmed fruit. Mine will have more micronutrients, and I'm trying to feed a family and friends, not hundreds of people. At least here in North America, it seems as if all the grocery store fruit has to not only look perfect, but look huge, and farmers with access to water, can achieve that until the water runs out. By teaching my trees to do "adequately" with minimal water, I am building resilience.
