The n-conjecture is a generalization of abc and basically says that the if $a_1 + \ldots + a_n=0$, no proper subsum vanishes and $a_i$ are coprime, then the radical of $a_1\cdots a_n$ can't be too small.
Let $f(x_1,\ldots,x_m)=0$ be possibly reducible projective variety.
Take $a_i$ in the n-conjecture to be the monomials in $f$ (including coefficients).
If $f$ has $n$ monomials, the monomials are coprime at infinitely many integral points, no subsum vanishes and there isn't great discrepancy in the size of the monomials the n-conjecture implies the degree of $f$ is at most $(2n-5)m$.
This bound is sharp:
$$ x^9+y^9+3ax^3y^3z^3-a^3z^9=\left(-1\right) \cdot (z^{3} a - x^{3} - y^{3}) \cdot (z^{6} a^{2} + x^{3} z^{3} a + y^{3} z^{3} a + x^{6} - x^{3} y^{3} + y^{6})$$
Both factors of the RHS are genus $1$.
Let $f(x,y,z)=b_1 x^d+b_2 y^d+b_3 z^d+b_4 x^{d_1}y^{d_2}z^{d_3}$ and all $b_i$ are nonzero.
Q1 Can $f(x,y,z)=0$ have genus $0$ or $1$ component if $d>9$ ?
Q2 Does infinitely many coprime integral points on varieties with few monomials contradict other conjectures?
